Arnprior Battery Energy Storage Project
Arnprior BESS Connection 1

Project overview

Arnprior BESS Limited Partnership (the “Proponent”), a controlled subsidiary of PR Development LP (the “Qualified Applicant”), an affiliate of Potentia Renewables Inc., is proposing to construct the Arnprior Battery Energy Storage Project (“Arnprior BESS” or the “Project”) in the City of Ottawa.  The proposed Project is a lithium-ion battery energy storage facility sized to provide up to 50 MW over four hours, (200 Megawatt-hours). It occupies approximately 5 acres of land located on the northeast side of ON-17, just north of Galetta Sideroad.  An overview map of the project is on the right with a more detailed map below.

The Project originally considered two options to connect to the electrical grid. On October 23rd the Project decided to focus on Connection Option 1 and will no longer pursue Connection Option 2. For certainty, the Project is only proposing to connect to the Connection Point shown on the Detailed Map.

The Project will be participating in the 2023 Independent Electricity System Operators (“IESO”) Long-Term Request for Proposal (“IESO LT1 RFP). Arnprior BESS is designed with the intention of addressing the growing electricity needs of eastern Ontario. The IESO is forecasting a need for 4,000 MW by 2030 and is in the process of administering various procurement programs to address this need. 

The Project is also initiating a Class Environmental Assessment for Minor Transmission Facilities (“Class EA”), in accordance with the Ontario Environmental Assessment Act. Contingent on the outcome of the Class EA process, construction could begin in spring 2025 and is expected to be completed by the end of 2026.

community and indigenous engagement

Arnprior BESS has designed a Community and Indigenous Engagement Plan (“Engagement Plan”) for the Project to provide structured and proactive consultation and engagement with stakeholders throughout the Project’s development. We recognize that stakeholder input is an integral component of a successful project. This Engagement Plan follows the engagement requirements as outlined in Section 2.1(f)(i)(B) of the IESO LT1 RFP. The Engagement Plan has been updated to reflect recent consultation activities for the Project. 

The Project had its first Community Open House on Thursday, November 9, 2023 at the Fitzroy Harbour Hall in Fitzroy Harbour. Local communities and interested stakeholders had the opportunity to learn more about the proposed Project and speak directly with members of our Project team. 

The poster boards from the first Community Open House are now available below. Meeting minutes and notes will be posted soon. 

We strive to keep the community and interested parties up to date with Project information. If you have any questions or feedback, please reach out to us at info@arnpriorbess.ca.

community benefits

  • Long-Term Tax Revenue: Over the course of its life span, the Project will be a source of significant and reliable contributions to the Municipality’s tax base while requiring minimal municipal services. The Municipality can use the increased tax revenue to fund roads, schools and improve municipal services. 
  • Local Employment: Jobs created during construction will include those related to land surveying, road construction, concrete and aggregates supply, equipment installation, substation construction, electrical testing and technical commissioning to name a few. 
  • Boosting the Economy: We will seek to source construction site services, materials, and contractors locally. Workers may also require local accommodation and services while working on the Project. In addition to the direct jobs, the Project will increase electrical capacity enabling further investment in eastern Ontario. 
  • Reducing Emissions – The Project will also help to reduce Ontario’s emissions by limiting the need to run natural gas generators during times of peak loads.  
  • Resilient Electricity: The project will increase electrical capacity enabling future sustainable economic growth within the City.
  • Community Benefit Fund: Through consultation with the City and local stakeholders PRI intends to establish a community benefit fund that will support a thriving community and vibrant countryside:
